A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/sec through a 1.5 in. diameter pipe. If the weight of the empty tank is 50 lbs, determine the scale reading at t=10 sec. What is the true weight of the water and tank at 10 sec? need the reading scale only I have the true weight of the water and tank 10 sec which is 203
A 10cm diameter vertical tank holds 20cm of water topped with 15cm of ethyl alcohol. The cylinder is rotated about its central axis at a rotation rate of 20 rad/s. (a) What will be the shape of the air-alcohol and alcohol-water interfaces (include ..
CPM Construction plans to buy a truck for $150,000 and sell it for $15,000 at the end of 5 years. The annual operating cost of the vehicle is $60,000. What is the present value of the truck
A car is traveling up a 3% grade on a road that has good, wet pavement. The engine is running at 2500 rpm. The radius of the wheels is 15 inches, the driveline slipage is 3% and the overall gear reduction ratio is 2.5 to 1
Let a one-dimensional velocity field be u = u(x, t), with v = 0 and w = 0. The density varies a ?-?0(2-cos(wt)) Find an expression for u(x, t) if u(0, t) = U.
The slope of the hill is such that for each 1.5 km of horizontal distance, the change in elevation is dz meter. Determine the maximum value of dz if the flow is to remain laminar, with a temperature of T=20°C and pressure all along the pipe is con..
These concentrations were measured when the trailers were 2 years old and the emission rate had significantly decreased by that time. New material rates as high as 290 mg/hr have been reported. Calculate the steady state HCHO concentration (ug/m3) re..
Classify the following soils using the given grain size distribution (ASTM system) and Atterberg Limits data:
Determine the value and location from point D of the maximum internal bending moment and shear force for the member. Take x = 2 ft. Be sure to draw complete free body diagram(s) for full credit.
A transit was set at point M and a leveling rod was held vertically at point N. The horizontal cross line of the telescope was inclined so the reading of the horizontal cross line on the rod was 12 ft.
The level of water in a city water tower is 125ft. above the ground. The tank is kept with an air space which can be pressurized with compressed air. It is important to maintain a pressure at the bottom of the tower at 75 psig
Steam enters an adiabatic turbine steadily at 3 MPa and 300 *C and leaves at 70 Kpa and 100 *C. If the power output of the turbine is 2 MW, determine a) the isentropic efficiency of the turbine and b) the mass flow rate of the steam flowing throug..
To avoid submergence the crest of the weir must be at least 0.05 m above the downstream water depth. Here we can assume that the depth downstream is equal to the normal depth. To simplify calculations we will assume that Cd = 0.7 Water depth over the..
